OBITUARY

Dennis John Conway, age 70, passed away at his home in San Jose, California, on July 25, 2026.

Dennis was preceded in death by his parents, Mary Ann and John Conway. He was the fifth of seven children and is survived by his siblings, James Conway and his wife, Eileen; Terry Conway and his wife, Judith Neafsey; Kevin Conway and his wife, Linda; Colleen Freeman and her husband, Greg; Eileen Seitz and her husband, Paul; and Patty Conway and her husband, John Burczak. He is also survived by 14 nieces and nephews, 14 great-nieces and great-nephews, and the many friends whose lives were enriched by his loyalty, generosity, and enduring friendship. Dennis affectionately called himself the “favorite uncle,” a title his nieces and nephews happily affirmed.

Dennis was born in Fort Dix, New Jersey, and grew up in Lyons, Illinois, a community that remained close to his heart throughout his life. He attended St. Hugh School in Lyons and maintained lifelong friendships with several classmates from his elementary school years. For Dennis, once someone became a friend, they remained a friend.

Dennis loved to travel and enjoyed exploring the world. His travels took him to memorable destinations, including many trips to Ireland, his ancestral homeland.

A lifelong and devoted Chicago Cubs fan, Dennis attended games whenever he returned to the Chicago area and traveled to Arizona for spring training. One of the great highlights of his life as a Cubs fan was attending a game during the historic 2016 World Series.

Dennis graduated from St. Ignatius College Prep in Chicago and earned a Bachelor of Science degree in Electrical Engineering from Southern Illinois University. He moved to San Jose, where he worked for 18 years at Hewlett-Packard. Throughout his career, Dennis continued to pursue advanced education and professional credentials. He became a Certified Quality Engineer through the American Society for Quality, earned a professional certificate in Strategic Decision and Risk Management from Stanford University, and completed both a Master of Science in Engineering and a Master of Business Administration at San Jose State University. He also became a Certified Public Accountant and volunteered with Tax-Aid.

Above all, Dennis was proud of his family and deeply supportive of those he loved. He faithfully celebrated births and baptisms, birthdays, weddings and anniversaries, graduations, professional accomplishments, and the many other milestones in the lives of his family members and friends. Dennis’s Catholic faith remained an important and sustaining presence throughout his life.

Dennis will be remembered for his intelligence, curiosity, love of travel, devotion to the Cubs, pride in his family, and remarkable ability to sustain friendships across the years and miles. He will be deeply missed.

Friends are invited to attend the 12:10 p.m. Mass at Old St. Patrick’s Catholic Church, 700 W. Adams Street, Chicago, on Monday, September 21st, to be followed by a blessing of the cremains at the church.
